Crit_period#

The age of onset of acquisition and ultimate level of attainment of second language learners in North America and Israel.

From the author: “In second language acquisition research, the critical period hypothesis (cph) holds that the function between learners’ age and their susceptibility to second language input is non-linear. This paper revisits the indistinctness found in the literature with regard to this hypothesis’s scope and predictions.”

Initialization#

library(fosdata)
data <- fosdata::crit_period

Accessing fields#

data <- fosdata::crit_period
aoa <- data$aoa # Just a random field in the dataset

Interactive R Sample#

LLM instructions#

If using an LLM, you can copy-paste the following instructions to accompany your prompt to inform the model of the fields and their types in the dataset.
